The site was identified as internationally important for bird conservation in 2009 because it was regularly supporting significant populations of the species listed below, meeting IBA criteria.

Populations meeting IBA criteria ('key species') at the site:

Species	Red List	Season (year/s of estimate)	Size	IBA criteria
Eurasian Curlew Numenius arquata	NT	breeding (1997–2005)	3–11 breeding pairs	B2
Common Kingfisher Alcedo atthis	LC	breeding (1994)	5–10 breeding pairs	C6
Bluethroat Luscinia svecica	LC	breeding (1995)	20 breeding pairs	C6

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2009. The most recent assessment (2013) is shown below.

State (condition of the key species' populations)
Species	Actual vs Reference (units)	% remaining	Result
Corncrake Crex crex	0 / 14 (breeding pairs)	0	very unfavourable
Eurasian Curlew Numenius arquata	0 / 7 (breeding pairs)	0	very unfavourable

Pressure (threats to the key species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	happen­ing now	whole popul­ation/area (>90%)	rapid deteri­oration (>30% over 3 gener­ations)	very high

Response (conservation actions taken for the key species and/or their habitats)
Designation	Planning	Action	Result
Not assessed	Not assessed	Not assessed	not assessed
